Abstract: Penetration of moisture and propagation of cracks is prevented in a polarizer. An adhesive is provided to cover one or more edges of the polarizer to seal the side section of the polarizer. The adhesive fills initial cracks to prevent the initial crack from being propagated to the inside of the polarizer. A protective film and the adhesive include a material having a hydrophobic characteristic. In a method of fabricating a polarizer, a polarizing film is shaped to form a polarizing layer, and a protective film is then attached by applying an adhesive onto the edges of the polarizing layer. Then, the adhesive is cured, and the protective film having the polarizing layer attached is processed, thereby dividing the protective film into a plurality of polarizers. The adhesive can firmly fix the crack since the adhesive is fills in cracks in the polarizing layer.

Abstract: A display device according to the present disclosure may be provided with a light path conversion protrusion on a lower surface of a cover window to suppress external light even for light incident at a side viewing angle, thereby improving contrast and visibility.According to the present disclosure, side-view angle incident light may be converted into the same incident light as that of vertical incident light, thereby providing an effect capable of preventing the reflection of incident light from a viewing angle as well as the vertical incident light.
